競技用ボートの固有振動数がピッチングに及ぼす影響把握

抄録

The pitching phenomenon of boat affects the muscle fatigue and rowing difficulty as well as the wave resistance. Initially, in this research, a pitching phenomenon was observed due to change the rowing rates by using a single scull boat. As a result, the amplitude in the specific rate increased. The next, for three different types of boat of the material, structure and weight, vibrations were analyzed. Therefore, the natural frequency affects the pitching, and then the tuning phenomenon of the forced vibration induced due to rate and natural vibration frequency hardly occurs structure of pitching phenomenon has been suggested.
